Which flap disc is best for grinding metal?



Flap discs are a great abrasive wheel for quick stock removal, providing grinding, blending and finishing with one product. They’re manufactured for use on both mild and stainless steel. Flap wheels made from zirconia (or zirconium) are better suited for use on most metals including stainless steel. Aluminum Oxide flap discs are suitable for most metals, but not for use on stainless steel applications.
